A patient visited his urologist for a cancer consultation and expressed concern about being able to perform after the operation. The patient was also worried about the chemotherapy. The doctor said, "I had bladder cancer a few years ago. Ten days after the operation I made passionate love with my wife, and forgot all my worries. Try it and see for yourself." Three weeks later the patient returns, and thanks the doctor effusively. The doctor says "I'm glad my advice helped." The patient thanks him again, and as he's leaving says "By the way Doctor, you have a really beautiful house."
